BACKGROUND/AIM: People with spinal cord injuries are at high risk of developing pressure ulcers. Wheelchair cushions that redistribute pressure are one prevention strategy to reduce the risk of pressure ulcers in this population. Currently, therapists have only limited evidence concerning the pressure redistribution qualities of wheelchair cushions to guide their cushion selection in clinical practice. The aim of this study was to compare the pressure redistribution qualities of two air-filled cushions currently recommended for people with spinal cord injuries.
A series of single case studies, based on the methodology used in a previous study, was undertaken on three inpatients with complete spinal cord injury. Interface pressure readings were compared between a Roho® and Vicair® cushion using the Xsensor® Pressure Mapping System. The Roho® cushion is comprised of a series of soft, flexible, inter-connected air cells, and the Vicair® cushion contains separate, sealed cells of air.
The Roho® cushion recorded significantly fewer cells with pressures ≥100 mmHg than the Vicair® cushion for the three participants.
This study has provided evidence that the Roho® cushion has superior pressure redistribution qualities than the Vicair® cushion for a small sample of patients with complete spinal cord injury.
背景/目的：脊髓损伤患者发生压疮的风险很高。能重新分配压力的轮椅坐垫是降低该人群压疮风险的一种预防策略。目前，治疗师在临床实践中选择轮椅坐垫时，关于轮椅坐垫压力重新分配特性的证据有限。本研究的目的是比较目前推荐给脊髓损伤患者的两种充气坐垫的压力重新分配特性。
基于之前一项研究中使用的方法，对三名完全性脊髓损伤的住院患者进行了一系列单病例研究。使用Xsensor®压力映射系统比较了罗霍（Roho®）坐垫和维凯尔（Vicair®）坐垫的界面压力读数。罗霍（Roho®）坐垫由一系列柔软、灵活、相互连接的气囊组成，维凯尔（Vicair®）坐垫包含独立的密封气囊。
对于三名参与者，罗霍（Roho®）坐垫记录的压力≥100 mmHg的气囊数量明显少于维凯尔（Vicair®）坐垫。
本研究提供了证据，对于一小部分完全性脊髓损伤患者，罗霍（Roho®）坐垫的压力重新分配特性优于维凯尔（Vicair®）坐垫。
